Timing Chain Upper Cover (2) - Remove
- Timing Chain Upper Cover Seal (1) - Remove and DISCARD
Install the EN-52461 Cam Phaser Torque Reaction Tool (2) to the 2 EN-52461-100 Adapter Cam Phaser Torque Reaction Tool (3).
- Hand tighten the 2 bolts (1, 4) of EN-52461 Cam Phaser Torque Reaction Tool.
Install the EN-52461 Cam Phaser Torque Reaction Tool (5) along with the 2 EN-52461 Cam Phaser Torque Reaction Tool (2, 3) to the camshaft carrier.
- Tighten the 2 bolts (1, 4) of EN-52461-100 Adapter Cam Phaser Torque Reaction Tool.
- Tighten the 2 bolts from the EN-52461 Cam Phaser Torque Reaction Tool to the 2 EN-52461 Cam Phaser Torque Reaction Tool that were hand tightened.
Install the EN-52461-1 Holder (1) to the holes in the camshaft sprocket.
- Check that the EN-52461-1 Holder (1) sits correctly in the hole of the camshaft sprocket.
- To take tension of the actuators and loosen timing chain. Turn the exhaust side counter clockwise to 6 N.m (53 lb in) and tighten bolt (3) just enough to hold the EN-52461-1 Holder (1) in place.
- Turn the intake side counter clockwise to 6 N.m (53 lb in) and tighten bolt (4) just enough to hold the EN-52461-1 Holder (1) in place.
Engine Coolant Temperature Sensor Electrical Connector (2) - Disconnect
Engine Coolant Temperature Sensor (1) - Remove
Engine Front Cover Bolt (1) - Remove [9x]
- Engine Front Cover (2) - Remove and DISCARD
Timing Chain Tensioner Bolt (1) - Remove [2x]
- Timing Chain Tensioner (2) - Remove
- To set the NEW timing chain tensioner follow next steps if needed.
Remove the timing chain tensioner plunger (1) from the timing chain tensioner body (2).
- NOTE:
The ratchet mechanism will lock into place when inward pressure is released after it is turned clockwise until it is fully retracted.
Use the J-45027-1 Tensioner Tool Handle (1) to press the ratchet mechanism of the timing chain tensioner plunger (2) inward while rotating it clockwise.
- Release pressure on the ratchet mechanism of the timing chain plunger (2) until it locks into place.
- Remove the J-45027-1 Tensioner Tool Handle (1).
Install the timing chain plunger (1) into the timing chain tensioner body (2).
- NOTE:
Applying pressure to the timing chain tensioner plunger assembly will unlock the tensioner, it will then fully extend if pressure is released prior to installing the EN-955-10A Locking Pin and will need to be reset again.
Push in and hold the timing chain tensioner plunger, insert the EN-955-10A Locking Pin (1) into the timing chain tensioner (2), then release the timing chain tensioner plunger.
Leave the oil filter in place, or oil will continue to drip.
The timing chain tensioner plunger is spring loaded, hold the plunger in place as tensioner is removed to prevent losing components of the timing chain tensioner.
If the ratchet mechanism does not lock into place and begins to extend outward, reapply inward pressure with clockwise rotation until the ratchet mechanism will not rotate further, then release into the locked position.
